This patch series optimized CRC32C calculations with PCLMULQDQ instruction for crc32c-intel module. It speeds up the original implementation by 1.6x for 1K buffer and by 3x for buffer 4k or more. The tcrypt module was enhanced for doing speed test on crc32c calculations. Tim Signed-off-by: Tim Chen <redacted>
All applied. Thanks Tim! -- Email: Herbert Xu [off-list ref] Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
